HOLDER FOR COLLA PSIBLE TUBES Application filed March '23, 1928, Serial No. 264,257. Renewed ama 3,1930.

My invention relates particularly to de' vices of the character set forth in my Patent 1,617,917 and myapplication179.,307, filed March 29, 1927, of which latter application this present application is a continuation in part. 7v

The principal object of my presentinvention is'to simplify and cheapen the construction. I In its preferred form the casing is provided with a readily detachable front to facilitate'access andthe insertion and removal of compressible tubes. The compressing jaws are carried by a slide which is guided in the casing, the latter being provided with integral flanges which serve as the guides. The jaws are operated by swinging bars which are so constructed and arranged that the finger levers may be connected directly to the box. The tube is inserted between the jaws and has its nozzle or neck mounted in the bottom of the casing and closed by suit able means such as a spring pressed valve. Fig. 1 is a perspective view of one form of device involving my invention.

Fig. 2 is a plan View and sectionon the plane of the line 2-2 of Fig. 6, showing the finger levers in full lines in'the normal position of rest and in dotted lines showing the position of the finger levers when the tube has been compressed.

Fig. 3 is a plan view and section on the plane of the line 33 of'Fig. 6 showing the parts in the position in which the tube is compressed. f

Fig. 4 is a perspective view of the compressing jaws, the carrier slide and the I "closure 33 which has a spr ng pressed sleeve swinging bars for operating them.

Fig. 5 is a front view of the device with the front'cover'removed. v

Fig. 6 is'a vertical sectionand sid'eelevation, the-section being on the 'plane of the line 66 of Fig. 5. Fig. 7 is a bottom view;

Fig. 8 is a fragmentary front view of the lower end with a modified form of closure.

The casing 10 is preferably formed of sheet metal, the back and sidesbeing integral and provided with inwardly turned flanges 11." The top 12 and the bottom 13 lines as'shown in Fig. open for use. 7

may be secured inplace in any suitable manner. The slide 14 carries the pivotal jaws 15 which are adapted to embrace'the opposite sides ofthe tube 16 as shown in Fig. K The slide is U-shaped in plan view and the side arms 17 fit the sides of the casing behind the flanges 11. Thus the walls and flanges of the casing form the guiding and supporting means for the slide 14. v The bowed spring-18 has its ends 19 engaged in recess or holes in the -lower edges of the jaws so as to tend to spread the jaws apart, as shown in Figs. 4 and5. The bars 20 are provided'with upper and lower pivot studs 21 and 22 which engage'in the top and 6 bottom plates 12 and 13. Finger levers 23 are secured directly to the upper ends of the bars 20 in any suitablemanner. The pressure of the spring 18 tends toopen up the. jaws and to'press the'bars 20 against the 7 flanges 11 when the parts are in the normal position of rest.

' Y The bottom plate is provide'dwith a funnel-like' recess 24 with a mouth piece 25 adapted to receive the neck 26 of the tubel6. This neck may be clamped in place by the thumb screw '27. I j

The closure 28 fits into'the neck or nozzle of thetube' so as to normally keep it closed. This closure is carried by a finger lever29 which is pivoted at 30, The angular hub 31 is kept under pressureof the leaf s'pring 32 which tends to holdit in the closed position shown in full lines in Fig. 6 or in the dotted InFig. 8 I have shown a modified form of 34. mounted on the upright rod 35. This spring tends t'okeepthe closure tight on its 0 seat. A finger piece 36may be provided to facilitatelowering the closure 33 and turning itto one side so asto admit the brush to the outlet of the tube.

To operate the device the neck of thetube 95 is'inserted in the mouth 25 and clamped in place by the screw 27, the upper end of the tube being inserted between the jaws 15 which are in their spread apart position. The

weight of the slide and jaws is supporte 11 109 a 6 when the tube is the tube itself. When it is desired to use the tube the closure 28 is dropped away from the outlet and the finger levers,23 are pressed toward each other by the operator. pressure is transmitted through the bars 20 and through the outerlower edges of the jaws 15 which are thus pressed downwardly against the sides of the tube causing some of the contents to be ejected.

The teeth 37 tend to bite into the walls of the tube and press'downward ly When the pressure on the finger leversis released the spring 18 returns the parts totheir normal position. The weight Ofthe slide and jaws is sufi icien't to cause them to feed downwardly slightly each time the tube has been compressed andthe finger levers released.

The front or cover plate 38 has top and bottom flanges 39 and/l0 which overlap the top and bottom plates of the casing. The sides are provided withinwardlypressed bosses 41 which are adapted to snap into recesses in the sides of the body of the casing to yieldingly hold the parts together. The upper end of the front is provided with slots or openings 41 for the finger levers.

It should be understood that various changes in construction may be made with out departing from the spirit or scope of my invention.
